0x0A. Python - Inheritance

As I am diving deeper in Object Oriented Programming (OOP) with python, this project introduce me to the concept of inheritance

Inheritance is a mechanism in which one class acquires the property of another class. For example, a child inherits the traits of his/her parents. With inheritance, we can reuse the fields and methods of the existing class. Hence, inheritance facilitates Reusability and is an important concept of OOPs.

Python has two built-in functions that work with inheritance:

• Use isinstance() to check an instance’s type: isinstance(obj, int) will be True only if obj.__class__ is int or some class derived from int.

• Use issubclass() to check class inheritance: issubclass(bool, int) is True since bool is a subclass of int. However, issubclass(float, int) is False since float is not a subclass of int.

In this project, I learnt:

• Why Python programming is awesome
• What is a superclass, baseclass or parentclass
• What is a subclass
• How to list all attributes and methods of a class or instance
• When can an instance have new attributes
• How to inherit class from another
• How to define a class with multiple base classes
• What is the default class every class inherit from
• How to override a method or attribute inherited from the base class
• Which attributes or methods are available by heritage to subclasses
• What is the purpose of inheritance
• What are, when and how to use isinstance, issubclass, type and super built-in functions
